The embodiment of the invention provides a brake lamp circuit capable of adjusting a display mode according to automobile brake force and a brake lamp. The brake lamp circuit capable of adjusting thedisplay mode according to the automobile brake force comprises a CAN bus receiving and transmitting circuit, an MCU calculation processing circuit electrically connected with the CAN bus receiving andtransmitting circuit, an LED constant current source circuit electrically connected with the MCU calculation processing circuit, a switch transistor circuit electrically connected with the MCU calculation processing circuit and an LED lamp display circuit electrically connected with the switch transistor circuit. The display number of the LED lamps can be controlled according to different brake force information of an automobile, the purposes of dynamic display and brightness change are achieved, a driver of a rear automobile is reminded whether the front automobile is in a brake state or notand whether the front automobile is in an emergency brake state or not, and then the driver of the rear automobile is reminded to take corresponding avoidance measures. Traffic accidents caused by the fact that rear vehicles do not notice brake signals of front vehicles are prevented.

    本发明实施例提供了根据汽车刹车力度调整显示方式的制动灯电路及制动灯,根据汽车刹车力度调整显示方式的制动灯电路包括CAN总线收发电路、与CAN总线收发电路电连接的MCU计算处理电路、与MCU计算处理电路电连接的LED恒流源电路、与MCU计算处理电路电连接的开关晶体管电路以及与开关晶体管电路电连接的LED灯显示电路。本发明能够根据汽车不同的刹车力度信息,控制LED灯的显示数量,达到动态显示以及亮度变化的目的,以提醒后方车辆前车正在刹车以及是否处于紧急刹车状态,进而提醒后方车辆驾驶员采取相应的规避措施,以防后方车辆没注意到前车的刹车信号,造成交通事故。
